Queen's Gambit Declined


The Queen's Gambit Declined is a chess opening in which Black declines a pawn offered by White in the Queen's Gambit:
This is known as the Orthodox Line of the Queen's Gambit Declined. When the "Queen's Gambit Declined" is mentioned, it is usually assumed to be referring to the Orthodox Line; see "Other second moves for Black" below for other moves.
The most common continuation is 3.Nc3 Nf6, after which White may continue with 4.Bg5, leading to the traditional line, 4.cxd5, the Exchange Variation, and 4.Nf3, the Three Knights Variation.
The Orthodox Line can be reached by a number of different, such as 1.d4 Nf6 2.c4 e6 3.Nf3 d5; 1.d4 e6 2.c4 d5; 1.c4 e6 2.Nc3 d5 3.d4; 1.Nf3 d5 2.c4 e6 3.d4; and so on. Of the 34 games played in the 1927 World Championship between Alexander Alekhine and José Raúl Capablanca, all except the first and third began with the Queen's Gambit Declined.

General concepts

Playing 2...e6 releases Black's, while obstructing Black's. By declining White's temporary pawn sacrifice, Black erects a solid position; the pawns on d5 and e6 give Black a foothold in the. The Queen's Gambit Declined has the reputation of being one of Black's most reliable defenses to 1.d4. In this situation, White will try to exploit the passivity of Black's light-squared bishop, and Black will try to release it, trade it, or prove that, while passive, the bishop has a useful defensive role.
An eventual...dxc4 by Black will surrender the center to White, and Black will usually not do this unless Black can extract a concession, usually in the form of gaining a tempo, by capturing on c4 only after White has played Bd3 first. In the Orthodox Line, the fight for the tempo revolves around White's efforts to play all other useful developing moves prior to playing Bd3. Black will often aim for the pawn break...c5 in this opening, which often leads to one or the other side accepting isolated or hanging pawns in exchange for dynamic compensation.

Traditional line: 3.Nc3 Nf6 4.Bg5

4.Bg5 was the most common move in the 20th century, although 4.exd5 has gradually become more common. Black's most common reply is 4...Be7, where play typically continues 5.e3 0-0 6.Nf3, or White may opt for 5.Nf3 and 6.e3. It is also commonly reached by transposition from the Three Knights Variation.
If Black chooses to include 6...h6, this is considered the Neo-Orthodox Variation, which leads to the Tartakower Variation, Lasker Variation, and Anti-Tartakower Variation; these variations are also commonly reached via 5...h6 6.Bh4 0-0 7.Nf3, but 4...h6 is weak due to 5.Bxf6, where 5...gxf6 6.cxd5 exd5 gives Black doubled isolated pawns and 5...Qxf6 6.cxd5 exd5 7.Nxd5 loses a pawn. Omitting...h6 is characteristic of the Classical Variation.

Classical Variation: 4...Be7 5.e3 0-0 6.Nf3 Nbd7

The Classical Variation, also known as the Orthodox Defense, most often continues 7.Rc1 c6, where White's most common move is then 8.Bd3. After 8...dxc4 9.Bxc4, Black has surrendered the center and stands somewhat cramped, but has succeeded in making White lose a tempo by playing Bd3 before Bxc4. White will try to use the advantage in space to attack, whereas Black will try to keep White at bay while striking back at the center. Capablanca's main idea here was the freeing maneuver 9...Nd5 10.Bxe7 Qxe7 11.0-0 Nxc3 12.Rxc3 e5 13.dxe5 Nxe5 14.Nxe5 Qxe5 15.f4 Qe7, which has led to a number of exchanges in the center, though Black must exercise care even in the wake of this simplification. This line was once so frequently played that it has a separate code in ECO, though the lack of active counter play for Black has made the main line of the Orthodox a backwater in modern practice.
White also often plays either 7.Qc2, the Rubinstein Variation, or 8.Qc2.

Tartakower Variation: 6...h6 7.Bh4 b6

The [|Tartakower Variation] or Tartakower–Makogonov–Bondarevsky System is one of the most solid continuations for Black.

Lasker Variation: 6...h6 7.Bh4 Ne4

The [|Lasker Variation], is also a solid line, often leading to the exchange of two sets of minor pieces. It was this line that Viswanathan Anand chose in the final game of the World Chess Championship 2010 in order to defeat Veselin Topalov and retain the world championship. The typical continuation is 8.Bxe7 Qxe7.

Anti-Tartakower Variation: 6...h6 7.Bxf6

Also known as the Anti-Tartakower–Makogonov–Bondarevsky, this line was extensively tested in the Kasparov-Karpov matches in 1980s. To this day Black has no problems in this line despite being tested at the highest levels. More recently, Boris Gelfand defended the Black side of this variation in the 2011 candidates matches which eventually he went on to win. For example, in the third round of the final candidate match, he forced White to accept a draw in 14 moves with a very strong novelty.

Cambridge Springs Defense: 4...Nbd7 5.e3 c6 6.Nf3 Qa5

The Cambridge Springs Defense was introduced more than a century ago, and is still played. After 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5, 4...Nbd7 sets up the Elephant Trap, but if White avoids it, the common continuation 5.e3 c6 6.Nf3 allows Black to play 6...Qa5, intending...Bb4 and possibly...Ne4, with pressure along the a5–e1 diagonal. This Black defense is popular among amateurs because there are several traps White can fall into, for example 7.Nd2 7...Bb4 8.Qc2 0-0 and here 9.Bd3 loses since 9...dxc4 10.Bxf6 cxd3! 11.Qxd3 Nxf6 wins a piece for Black.

Exchange Variation: 4.cxd5

After 4.cxd5, the usual continuation is 4...exd5 5.Bg5. White has a pawn majority in the center, but Black has a pawn majority on the. This pawn structure gives White the opportunity to either advance the center pawns by means of Nge2, f2–f3, followed by e2–e4, or play for a by means of the plan Rb1, followed by b2–b4–b5, then bxc6 in order to create a weak pawn at c6. While Black can play...cxb5, or recapture on c6 with a piece, each of these possibilities is even less desirable than the backward pawn in the open file. For Black, exchanging at d5 has released the light-squared bishop and opened the e-file, giving Black the use of e4 as a springboard for central and play. While chances are balanced, Black is usually more or less forced to use the superior activity to launch a piece attack on White's king, as the long-term chances in the QGD Exchange structure favor White. The following games are model games for White:
  • Central pawn advance: Carlsen–Jakovenko, Nanjing 2009
  • Minority attack: Evans–Opsahl, Dubrovnik 1950
Black's fifth move must respond to White's threat of 6.Bxf6 Qxf6 7.Nxd5, winning a pawn, or 6...gxf6, inflicting doubled isolated pawns. The most common replies, 5...c6 and 5...Be7, usually transpose to the same line. 5...Bb4+, 5...Nbd7, and 5...Be6 are notable alternatives. After 5...c6, the main line continues 6.e3 Be7 7.Bd3 Nbd7 8.Qc2 0-0, followed by either 9.Nf3 or 9.Nge2, and then, regardless of White's ninth move, 9...Re8 10.0-0 Nf8, followed by 11.h3 and 11.f3. The resulting two positions are also often reached by many other move orders. After this point, many different moves are common, with no clear main line.
Two possible deviations from the line include 6.Qc2, the Reshevsky Variation, and 6...Bf5, which often leads to an after 7.Qf3 Bg6 8.Bxf6 Qxf6 9.Qxf6 gxf6. Another possibility is to play...h6 at some point. The most common such line, also commonly reached by other move orders, is 5...c6 6.e3 h6 7.Bh4 Be7 8.Bd3 0-0 9.Nge2 Re8 10.0-0 Nbd7 11.Qc2. Although 11...Nf8, similarly to the lines without...h6, is possible, 11...Nh5, 11...Ne4, and 11...a5 are more commonly played.
Black also has the option to play 4...Nxd5 instead of the more common 4...exd5, which most often ends up transposing to the Semi-Tarrasch Defense after 5.e4 Nxc3 6.bxc3 c5 7.Nf3, though White may play 7.Rb1 or 7.a3.

Three Knights Variation: 4.Nf3

The [|Three Knights Variation] of the QGD is more often reached from the move order 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3, played to avoid the Nimzo-Indian Defense and the Exchange Variation of the QGD. Black has a few options in response. After 4...Be7, 5.Bg5 transposes to the traditional line of the Queen's Gambit Declined, but White can avoid this, most notably with 5.Bf4.

Ragozin Variation: 4...Bb4

The Ragozin Variation occurs after Black plays 4...Bb4 in the Three Knights Variation. White has the main options of 5.Bg5, 5.cxd5, and 5.Qa4+, the Alekhine Variation, with the usual continuation 5...Nc6 6.e3 0-0 and then 7.Qc2 or 7.Bd2.
After 5.Bg5, Black has the options of 5...h6, 5...Nbd7, and 5...dxc4, transposing to the Vienna Variation, with the common continuation 6.e4 c5 7.Bxc4 cxd4 8.Nxd4. After 5...h6, the usual continuation is 6.Bxf6 Qxf6 7.e3 0-0 8.Rc1 dxc4 9.Bxc4 c5 10.0-0 cxd4 11.Ne4 Qe7. 5...Nbd7 most often continues 6.e3 c5, the Westphalian Variation, or the same moves after an exchange, 6.cxd5 exd5 7.e3 c5.
After 5.cxd5, the usual continuation is 5...exd5 6.Bg5 h6 7.Bh4 0-0 8.e3 Bf5. This avoids the potential transposition into the Vienna.

Semi-Slav Defense: 4...c6

The Semi-Slav Defense occurs after Black plays 4...c6 in the Three Knights Variation.

Semi-Tarrasch Defense: 4...c5

The Semi-Tarrasch Defense occurs after Black plays 4...c5 in the Three Knights Variation.
An important line in this variation is the Endgame Line where the game continues: 5.cxd5 cxd4 6.Qxd4 exd5 7.e4 dxe4 8.Qxd8+ Kxd8 where the queens get traded off in a similar fashion to the Endgame in the Berlin Defense, resulting in a drawish position. This line has been played by top grandmasters such as Wesley So, Anish Giri, and Magnus Carlsen aiming for a draw. There is also the [|Exchange Variation] where the game continues 5.cxd5 Nxd5 6.e4 Nxc3 7.bxc3 cxd4 8.cxd4, which has been used by the likes of Ding Liren, Anish Giri, Vladimir Kramnik, and Magnus Carlsen.

Harrwitz Attack: 4...Be7 5.Bf4

This variation is also a popular line. Placing the bishop on g5 allows Black to exchange more freely with moves like Nf6–e4, as seen in the Lasker Defense. The move Bf4 is designed to restrict Black's opportunities in this way, as well as reducing opportunities to gain the. Play usually continues with 5...0-0 6.e3 c5 7.dxc5 Bxc5. Peter Leko, usually an e4 player, used this variation as White to beat Vladimir Kramnik in their 2004 World Championship Match. Bobby Fischer played the line in game 14 of his 1972 match against Boris Spassky.

Vienna Variation: 4...dxc4

The Vienna Variation occurs after Black plays 4...dxc4 in the Three Knights Variation. The main line of the Vienna continues as 5.e4 Bb4 6.Bg5. White's pawns or pieces occupy the central squares in exchange for long-term pawn structure weaknesses. An instance of Vienna Variation played at the highest level was Fine–Euwe, AVRO 1938. The Quiet Variation of the Vienna Variation occurs after 5.e3.

Other third moves for Black

After 3.Nc3, Black has several common alternatives to 3...Nf6:
  • 3...c5. Striking back in the center early, it often leads to Black accepting an.
  • 3...Be7. Sometimes, this transposes to positions arising from 3...Nf6, and has the advantage, from Black's standpoint, of avoiding the main line of the Exchange Variation arising after 3...Nf6 4.cxd5 exd5 5.Bg5. In many cases, the game will simply transpose into the traditional line after 4.Nf3 Nf6 5.Bg5, or, White can play 4.cxd5 exd5 5.Bf4 c6 6.e3. The continuation 6...Bf5 7.g4 became a topical line after its adoption by Mikhail Botvinnik in his 1963 title match with Tigran Petrosian. 6.Qc2 is also popular. These exchange lines are more popular than transposing at top level.
  • 3...c6, usually signalling Black's intention to enter the Noteboom Variation after 4.Nf3 dxc4, or the Semi-Slav after 4...Nf6. White has alternatives to 4.Nf3 such as the Marshall Gambit 4.e4; or 4.e3 which may lead to the Stonewall Dutch after...f5 or transpose to the Semi-Slav.
  • 3...Bb4 intends to transpose to the Ragozin Variation, although White has various options to avoid this transposition. For instance, one drawback with this move is that after the moves 4.a3 Bxc3+ 5.bxc3 Nf6 6.e3 it allows White to achieve the pawn structure seen in the game Botvinnik–Capablanca, AVRO 1938, which is often considered somewhat advantageous for White.
  • 3...a6, which gained some interest in 2021 after being adopted by World Champion Magnus Carlsen. The move threatens...dxc4 followed by...b5, attempting to hold on to the pawn. For this reason, White usually plays cxd5 first.

Other third moves for White

White also commonly plays 3.Nf3, which usually transposes to the Three Knights Variation after 3...Nf6 4.Nc3 or to the Catalan Opening after 3...Nf6 4.g3. 3...Nf6 4.Bg5 usually transposes to the traditional line after 4...Be7 5.Nc3 or 4...Be7 5.e3 0-0 6.Nc3. Black also may play 3...c6, an accelerated Semi-Slav Defense; 3...c5, the Pseudo-Tarrasch Defense; 3...dxc4, transposing to the Queen's Gambit Accepted; or 3...a6.
Other third moves for White are rare:
  • 3.g3 usually transposes to the Catalan Opening after 3...Nf6, but gives Black the option of an independent line typically continuing 3...dxc4 4.Bg2 c5 5.Nf3 Nc6 6.Qa4 cxd4 7.Nxd4 Qxd4 8.Bxc6+ Bd7 9.Be3 Bxc6 10.Qxc6+ bxc6 11.Bxd4 Bb4+.
  • 3.e3 is a quiet line where White's queen's bishop is kept inside White's. Play may transpose to the Semi-Slav Defense.
  • 3.cxd5 is a rarely seen accelerated version of the Exchange Variation. After the usual 3...exd5 4.Nc3, Black can transpose to the standard Exchange Variation with 4...Nf6, but 4...c6 is a common move that avoids transposing.

Other second moves for Black

In its broadest sense, the Queen's Gambit Declined is any variation of the Queen's Gambit in which Black does not play...dxc4; however, variations other than 2...e6 have their own names and are usually treated separately. They include:
